Kendall Jenner, Cara Delevingne, Gigi and Bella Hadid, and Hailey Baldwin were just a few of the handful of models and celebrities that went on a Karl Lagerfeld-hosted Chanel boat party down the Hudson River last night in NYC, and it looks like the bash was a complete blast!

We wonder how Kenny felt about her momager Kris Jenner being in attendance, though! It's got to be slightly annoying to have your mother tag along everywhere you go when you're trying to make a name for yourself, but the Kardashian matriarch seems to fit in with the cool crowd. The 59-year-old even took the opportunity to pose for pics with Katy Perry, who she previously spent time with at Paris Fashion Week.

Gwen Stefani and baby Apollo are just the cutest duo ever! The mother/son team were decked out to head to Gwen's parents' house in Los Angeles. Earlier in the day, the 45-year-old and her youngest made a trip to the acupuncturist.

For the day's events, the mom-of-three opted for a pair of plaid harem pants and a white tank. We dream of Gwennie!

Similarly, her 13-month-old was dressed in a plaid diaper cover and funky t-shirt. That's one stylish baby!

Vanessa Hudgens decided to do some reflecting back on her failed relationship with High School Musical co-star to the New York Times, and the actress revealed that she struggled with insecurities over her actor beau's legions of admiring female fans.

"I went through a phase when I was really mean because I was so fed up. Girls were running after him, and I was giving them death stares. Then I realised that's not what that's about. 'Spread the love, be a good person, they support you, be nice,'" the Spring Breakers star confessed to the outlet.

Nowadays, the brunette beauty's spirituality and sense of female empowerment have made handling life in the limelight a lot easier.

"I used to be on the fence about it just because I feel like it gets to a certain place where it almost has the reverse effect, where it’s so overpowering and so aggressive that it’s like rather than just standing up for female pride and female rights, it becomes, like, ‘I am the man.’ But now I feel like there’s this new wave of feminists coming up that are truly about equal rights for women. I mean, Beyoncé is, like, killing the game, and I love her," she admitted about her stance on feminism.

Bruce Jenner secretly underwent a breast augmentation two weeks ago, which was one of the final steps in making the former Olympian's gender reassignment complete.

"Bruce had silicone breast implants put in a few weeks ago. He went with a smaller implant because he didn’t want to look ridiculous," a source dished to Radar.

"Recovery hasn’t been that difficult, but Bruce has had to sleep in a recliner to help with the healing. He’s not allowed to lift anything, and he has to wear a bra 24/7, but he’s expected to resume normal activities in the next six weeks. He has been emotional, but finally feels like this is the body he has meant to have," the source added.

The reality star's final operation to make his transition complete is set to take place in May or June, according to sources, and he hopes to be fully recovered in time to make his big debut as a woman contestant on the fall season of Dancing With The Stars. "This is a very exciting but scary time for Bruce​," the insider revealed.

We applaud her for having the bravery to follow her heart! Bravo Belinda!

At first we thought Joel Madden and a dressed-down Nicole Richie were arriving at Los Angeles International Airport last night, but after zooming in a bit we realized that it was actually the family's nanny!

Joel pushed son Sparrow in a luggage cart while the nanny held on tight to little miss Harlow, and the group were returning from Australia, where Joel hosts The Voice. Nicole was visiting Joel in Australia, so we're not sure where she was yesterday, but she recently revealed that she's grown quite accustomed to traveling there with the kids to be with her hubby.

"I feel very close to Australia," Nic told The Sydney Morning Herald earlier this month. "I really do feel like it's my second home. We've spent so much time there, Joel is an honorary Australian. So I'm going to ride on his coattails there and I just assume that I'm an honorary Australian also."

Well Zayn certainly isn't wasting any time! Less than a week after making the Internet cry by leaving One Direction, the former boy bander has a new song, "I Won't Mind."

British music producer Naughty Boy, who has worked with Sam Smith and Emeli Sande, released Zayn's first solo work on Monday. The 22-year-old was said to have joined the producer in the studio over the weekend and recorded the moody tune. Clearly Naughty Boy couldn't wait to share the demo with the world. Along with the song, Naughty Boy tweeted some digs at One Direction and wrote, "Let the music do the talking guys. thank us later. :) x." Naughty Boy also tweeted at Zayn, "You're the most important part of this jigsaw" and "Respect yourself enough to walk away from anything that no longer serves you, grows you, or makes you happy."

It looks like Louis Tomlinson didn't appreciate the jabs and tweeted at Naughty Boy, "Wow @NaughtyBoyMusic you're so inconsiderate pal , seriously how f*cking old are you ? Grow up ! #masterofallwisdom." But it seems like the producer should have waited until things have cooled down on the Internet because 1D fans are rabid! Less than 12 hours after posting, the song was removed from SoundCloud and there's been a Twitter backlash against the producer and his criticism of Zayn's former band.

Meanwhile, One Direction is moving on without their fifth member, planning on an upcoming tour and getting ready to release a new album. Zayn who?!

When we polled our X17 readers yesterday and asked if you'd buy 1D's next album even though Zayn is no longer with the band, 65% of you said yes while 35% of you said no way.

UPDATE:
The song in question is actually an old song that recorded for One Direction's aptly named last album, FOUR, reports the Daily Mail.

The insider said, "It's important fans know this isn't a solo Zayn song or even representative of material he might record in the future. If you listen to the track it is clearly a song written with One Direction in mind for their last album. It's not new, nor is it a Zayn Malik solo track."

Between making an appearance at Jay Z's music streaming launch party and then stopping by Opening Ceremony for some retail therapy, Rihanna was a busy bee yesterday!

Bad Gal RiRi wore daisy dukes and a bra, and she accessorized with a hat and a crazy trench coat. Not too long ago she revealed to Vogue that if she wears a bra, she doesn't wear a shirt and if she wears a shirt she doesn't wear a bra. At first we were a bit skeptical, but we haven't caught her wearing both a bra and a shirt for quite some time now!

And speaking of Jay Z's new service, Rihanna changed her Twitter banner last night to support Tidal, which aims to put more money in the pockets of the artists. RiRi tweeted, "NAVY, turn the tide…#MakeMusicHistory #TurnitBlue #TIDALforALL." Beyonce, Madonna, Calvin Harris, Diddy and Kanye West also followed suit, and all of the stars have been promoting the crap out of the new streaming program. But will it swim or sink?

Jay Z launched a new music streaming service called Tidal, and even though we hadn't heard of it until just now, he had quite the star-studded turnout at the #TIDALforALL launch party last night in New York City!

Not only was Jay's wife Beyonce Knowles in almost every single photo from the event, but she hammed it up for the cameras when she posed with famous friends like Rihanna, Nicki Minaj and yup, even Madonna! Alicia Keys, Kanye West, Jack White, Usher, Daft Punk, Arcade Fire and Deadmau5 were also in attendance, so it was a pretty eclectic mix of artists!

Keys sang her praises for the service and told the attendees, "So we come together before you on this day, March 30th, 2015, with one voice in unity in the hopes that today will be another one of those moments in time, a moment that will forever change the course of music history. For today we announce of Tidal, the first ever artist-owned, global music and entertainment platform."

Earlier this year Jay Z purchased the Swedish tech company Aspiro for $56 million and put them in charge of Tidal's logistics, and the members of Daft Punk were reportedly heavily involved in the marketing angle for the service. And in case you were wondering, the musicians involved do stand to make more of a profit from this streaming service than they would from Spotify, as there is no free tier. As if Jay and Bey needed to get any richer!
